Epidemiology and genomics of a slow outbreak of methicillin-resistant (MRSA) in a neonatal intensive care unit: Successful chronic decolonization of MRSA-positive healthcare personnel.

Objective: To describe the genomic analysis and epidemiologic response related to a slow and prolonged methicillin-resistant (MRSA) outbreak.

Design: Prospective observational study.

Setting: Neonatal intensive care unit (NICU).

Infection prevention strategies are highly protective in COVID-19 units while main risks to healthcare professionals come from coworkers and the community.

Background: Early evaluations of healthcare professional (HCP) COVID-19 risk occurred during insufficient personal protective equipment and disproportionate testing, contributing to perceptions of high patient-care related HCP risk. We evaluated HCP COVID-19 seropositivity after accounting for community factors and coworker outbreaks.

Methods: Prior to universal masking, we conducted a single-center retrospective cohort plus cross-sectional study.

Evaluation of the National Healthcare Safety Network standardized infection ratio risk adjustment for healthcare-facility-onset infection in intensive care, oncology, and hematopoietic cell transplant units in general acute-care hospitals.

Objective: To evaluate the National Health Safety Network (NHSN) hospital-onset Clostridioides difficile infection (HO-CDI) standardized infection ratio (SIR) risk adjustment for general acute-care hospitals with large numbers of intensive care unit (ICU), oncology unit, and hematopoietic cell transplant (HCT) patients.

Design: Retrospective cohort study.

Setting: Eight tertiary-care referral general hospitals in California.

Reductions in Clostridium difficile Infection (CDI) Rates Using Real-Time Automated Clinical Criteria Verification to Enforce Appropriate Testing.

PCR testing identifies both colonized and infected patients, making it critical to only test patients that meet clinical criteria for infection (CDI). We implemented an automated order-entry protocol that reduced inappropriate testing by 64% and hospital-onset (HO) CDI Standardized Infection Ratio (SIR) from 1.62 to 0.
